My view appears twice

As wiredesignz was telling you, you have double output because the "index" method is called twice : once when the object is created, and once when code igniter, through the routing process, call the default method. To be a little more explicit :

Code:

class testme {

function testme() {
   echo "hi there !";
}

}

$foo = new testme;

This code will echo "hi there !";

And now if you try :

Code:

class testme {

function testme() {
   echo "hi there !";
}

}

$foo = new testme;
$foo->testme();

This code will echo "hi there !hi there !";

When you have a controller with "index" as the class name , and you hit the URL http://youserver/index.php/index , codeigniter first create an object of your controller ( new Index() ) and because the default method called by codeigniter is "index", and because in your URL you didn't specify another method, codeigniter then call your "index" method once again.
Now if you create another method inside your controller, for example :

Code:

class Index extends controller {
  function index() {
    echo "in index ";
  }
  function foo () {
    echo "in foo ";
  }
}

and then you hit the URL http://youserver/index.php/index/foo it will echo "in index in foo ". To resume if I were you I wouldn't make a controller having "index" a the class name.
Good luck.
